mem, 205-edo

A mem divides one degree of 41-edo into 5 logarithmically equal parts. This is approximately the size of the JND (just noticeable difference). It therefore divides the octave into 41 * 5 = 205 equal parts.

The mem is therefore calculated as the 205th root of 2, or 2(1/205), with a ratio of approximately 1:1.00338692848311. It is an irrational number.
